My own Ruby Glow, since deceased, took temperatures as low as 28 degrees with out missing a beat..and then were killed outright ( roots and all) by a 26 degree event. I twas dead before the 24 degree night we had 2 weeks later. Fruit tasted metallic, but the flowers were worth it.

MIne don't like anything much below the 40's.. I'm afraid to expose them to much less.

I cut them back & bring them in during the winter- Just have to put chickenwire over the tops so the ferrets don't dig 'em up for me. I hang a "shop light" (1 each) verticly next to them- they seem to enjoy it.

Mine can take full sun at 105F- While I stay inside in the AC. I do water them every day as well tho.

Watch the leaves yelloing & falling off- check for spider mites. The red ones have destroyed one plant- but so far have left the others alone. Haven't found the 2 spotted ones on any passifloras .. Yet.

None have bloomed yet- But they did last year in the fall if I remember right.

Dunno if any of that helped..

Thank you both Wilmington and Krstofer. This info does help both from the heat/sun aspect as well as the cold. I am encouraged by the new growth on both plants. I'm figuring they are just acclimating to the zone change - I hope. Haven't noticed any leaf damage such as what you have shown us for the dreaded spider mites Krstofer. The leaves just look a little fried.

I'm hoping both will bloom when the weather cools down. I have 2 Vitifolias, a Scarlet Flame and a Coral GLow that I'm hoping will do the same on the cool down come fall.

Thank you again,
Debbie

P.S. Krstofer - loved the pics of your ferrets (what was it you called them in an earlier post Sumatran ???)
